Abstract
Transradial approach (TRA) is preferred over transfemoral approach (TFA) for percutaneous coronary interventions due to lower bleeding, vascular complications, and mortality, particularly in acute coronary syndrome. Radial access complications included intraprocedural events (spasm, dissection, and perforation) and postprocedural events (radial artery occlusion, hematoma, pseudoaneurysm, arteriovenous fistula, nerve injury, and infection). TFA remains necessary in certain settings but carries higher complication risk. Optimizing patient selection and procedural planning is essential to minimize vascular complications.
